Welcome to the Ott House, a circa 1845 home full of character, charm, and potential. If you've been looking for a property with history and good bones, this could be the opportunity you've been waiting for.

The spacious layout provides plenty of room for a growing family, a home-based business, or anyone looking to restore and personalize a piece of local history. Outside, you'll find a covered flagstone patio at the front of the home, a porch off the kitchen, and a generous lot with mature fruit trees and towering pines. The detached garage is also a rare find at approximately 43' x 32' and offering space for multiple vehicles, equipment, hobbies, or storage.

This home does require some TLC and a buyer with vision, but the character is here and there is plenty of potential. The property is serviced by a 100-amp panel, and buyers should know that some knob-and-tube wiring and asbestos-wrapped piping are present in the basement.
